ICD-10: H93.22

Diplacusis, classified under ICD-10 code H93.22, refers to a specific auditory phenomenon where a single sound is perceived as two distinct pitches or tones. This condition can significantly affect an individual's hearing experience, leading to challenges in sound localization and music perception.

Clinical Description of Diplacusis

Definition and Types

Diplacusis is characterized by the perception of a sound that is heard differently in each ear. This can manifest in two primary forms:

1. Diplacusis Dissonans: This occurs when the same sound is perceived at different pitches in each ear, leading to a dissonant auditory experience.
2. Diplacusis Echoica: In this variant, the sound is perceived as having a delay or echo effect, which can complicate the auditory experience further.

Causes

The underlying causes of diplacusis can vary widely and may include:

• Auditory Pathway Disorders: Issues within the auditory pathways, such as damage to the cochlea or auditory nerve, can lead to diplacusis.
• Hearing Loss: Individuals with varying degrees of hearing loss in each ear may experience diplacusis due to the differential processing of sound.
• Middle Ear Conditions: Conditions affecting the middle ear, such as otitis media, can also contribute to this auditory phenomenon.
• Neurological Factors: Neurological disorders that affect auditory processing may result in diplacusis.

Symptoms

Patients with diplacusis may report:

• Difficulty in distinguishing sounds, particularly in noisy environments.
• A sensation of sounds being out of tune or dissonant.
• Challenges in music appreciation, as melodies may sound altered or distorted.

Diagnosis and Management

Diagnostic Approach

Diagnosing diplacusis typically involves:

• Audiometric Testing: Comprehensive hearing tests to assess the degree and type of hearing loss.
• Tympanometry: Evaluating middle ear function to rule out conductive hearing issues.
• Otoacoustic Emissions: Testing to assess cochlear function.

Treatment Options

Management of diplacusis focuses on addressing the underlying causes and may include:

• Hearing Aids: For individuals with hearing loss, hearing aids can help balance sound perception between the ears.
• Auditory Rehabilitation: Therapy aimed at improving auditory processing skills.
• Medical Intervention: Treating any underlying conditions, such as infections or structural abnormalities in the ear.
